I am designing a home radio RA2 setup and am confronted with a slight problem. This is a home that is already wired. The family room has a 3-gang box with the main lights, fan control and fan light control. The homeowner wants to have a hybrid keypad in this box, due to its location in the room. How can I do this. The hybrid keypad will have to take the place of one of those and I don't have a good suggestion or remedy for this.
